DESCRIPTION

The DS89C21 is a differential CMOS line driver and

receiver pair, designed to meet the requirements of

TIA/EIA-422-A (RS-422) electrical characteristics

interface standard. The DS89C21 provides one driver

and one receiver in a minimum footprint. The device

is offered in an 8-pin SOIC package.

The CMOS design minimizes the supply current to 6

mA, making the device ideal for use in battery

powered or power conscious applications.

The driver features a fast transition time specified at

2.2 ns, and a maximum differential skew of 2 ns making the driver ideal for use in high speed

applications operating above 10 MHz.

The receiver can detect signals as low as 200 mV,

and also incorporates hysteresis for noise rejection.

Skew is specified at 4 ns maximum.

The DS89C21 is compatible with TTL and CMOS

levels (DI and RO).
